This blog consists of comments from my real blog, http://scienceblogs.com/stoat/, which I don't want to publish there.
Plus some other stuff convenient to place here.
And its becoming a convenient place for me to dump my comments on other blogs so I can find them again.

> Economic, social and environmental losses climb rapidly and nonlinearly with temperature change, and may already overwhelm the short-term benefits of fossil fuels

This looks like obvious nonsense to me. The short-term benefits of fossil fuels include an industrial society that allows 7 billion people to live, many in comfort. Removing those would lead to the society collapsing and billions starving. I can’t really tell what’s gone wrong with your statement: are you massively underestimating the gains, are you somehow saying we could keep those gains, today, without fossil fuels, or is your statement malformed? It claims to be a cost-benefit analysis. I think the present-day costs of GW are “small” when measured against the global economy.

It looks like your PCAGWH similarly fails; again, it’s hard to tell how you’re accounting for the balance.

This is rather disappointing. You’ve been writing and thinking about this stuff for a long time. We’ve been discussing it for ages. How can someone who is essentially “on your side” end up thinking you’re writing nonsense?
